I thought of a cool enemy. The are called Skulkers. They are kinda like shadows, in the dark they are impossible to see, and in light they are translucent. They look a little feline/humanoid. They are also very deliberate and quick, maybe coming in and hitting you once or twice then retreating and waiting. Kind of one of those frustrating opponents. and they drop materials needed to make Skulker armor. Which makes you harder to see, possibly harder for enemies to aim at, or even possibly invisible when you crouch.
well, i was more thinking they would live underground, where it is always dark, but maybe on some planets they come above ground, and the only think to protect yourself would be to use light. And maybe if you hit them with a beam of light, it stuns them for a few seconds
Seems like a good idea. Stalker like creatures roaming around you with claws that pounce on you that would make you squeal for mercy but this is too simple. The title is kind of plain since you just put "enemy suggestion", Try to be a little more creative about this. The concept of it is kind of good but don't just say "I don't care how it looks like", That's not such a good way to describe something like that. Try to give it a name. Describe it. It'll give the fear it needs to give to everybody. And if it doesn't have a form, make it morph into the nearest person he is to so that it would make him totally scary. The thread needs more Spazaz and a name. Do this and lots of perfect ideas will start spilling out okay !
